Description
技术领域
本发明属于建筑装饰材料加工领域,具体涉及一种地暖用多层实木复合地板的加工设备及方法。
背景技术
导热碳纤维是一种为热工设计所开发的高导热碳纤维材料,这种碳纤维在纤维方向上的导热系数可以超过铜,最高可以达到700W/mk,同时具有良好的机械性能、导电性能和优异的导热及辐射散热能力,由这种碳纤维制成的纤维状高导热碳粉本身呈纤维状,可以设计导热取向,这是区别于以往的碳粉和其它导热材料的最大不同和优势。
水玻璃化学式为R2O·nSiO2,式中R2O为碱金属氧化物,n为二氧化硅与碱金属氧化物摩尔数的比值,称为水玻璃的摩数。水玻璃可以涂刷材料表面,可提高材料的密实度、强度、抗渗性、抗冻性及耐水性等;将水玻璃、粒化高炉矿渣粉、砂及氟硅酸钠按适当比例拌合后,直接压入砖墙裂缝,可起到粘结和补强作用。用于配制速凝防水剂、硅胶、防火门的外表面等。
多层实木复合地板是一种性能较好的地板,与纯实木地板相比,不易变形,不易开裂,安装不需要龙骨,具有纯实木的性能。但是,这种多层实木复合地板如果用于地暖时,其导热性不是很好,影响了其应用范围。另外,多层实木复合地板在加工过程是,使用的脲醛树脂或酚醛树脂胶,其均含有游离甲醛,尤其用于地热采暖上,甲醛释放量会增加3-5倍,也影响了其使用。因此制备出能够导热且用胶量少的地暖用多层实木复合地板,解决市场的需要显得十分重要。找寻合适的导电剂是现阶段的研究热点,再结合导热碳纤维及水玻璃的作用,完善多层实木复合地板,制备出导热且用胶量少的地暖用多层实木复合地板。同时要发挥导热碳纤维的作用,需要设计一个新型的加工设备。
发明内容
本领域急需一种能够导热的且甲醛含量少的地暖用多层实木复合地板的加工设备,同时还需要一种采用上述加工设备制备导热性能好、且游离甲醛含量少的方法。
本发明是通过以下技术方案实现的。
一种地暖用多层实木复合地板的加工设备,包括有一密封容器,所述密封容器为长方体形,内腔大小与片板相等,上方带有密封盖,中部设置有密布有微孔的固定板,密封容器上下之间通过浸渍液管道连通有一循环泵;固定板的上方层叠有多层待浸渍片板,待浸渍片板的上方周边设置有压环。
优选地,所述固定板上的微孔的直径为2-4mm。
一种采用上述加工设备加工地暖用多层实木复合地板的方法,包括如下步骤:
(1)制备浸渍液:取水、导热碳纤维粉、氧化铝、二硫化钼粉,按照质量比100:4-6:2-3:2-3混合,制成浸渍液;
(2)选取不同的木材分别剖分为片板,片板分成面板、芯板和背板;
(3)将20-50层的片板放在密封容器的固定板上,压上压环加入浸渍液,开启循环泵加压循环1-2 h,使导热碳纤维粉纵向分布;
(4)浸渍完成后取出片板,90-100℃烘干,至水分含量为10-15%,得到浸渍片板;
(5)将步骤4的浸渍片板放在浓度为5-10%的水玻璃中浸泡4-6h,取出,在90-100℃下,烘干至水分含量为5-8%,得到备用片板;
(6)成型:将步骤5中的备用片板表面施树脂胶,定向铺装,热压成型,养护,得到多层实木复合地板;
(7)将所述多层实木复合地板进行砂光处理,然后由涂覆腻子、底漆、面漆装饰,开榫槽,分等,检验包装,入库。
优选地,步骤(1)中,所述导热碳纤维粉的直径20µm-50µm、长度1000µm-4000µm,氧化铝粉为过200-400目微米级粉,二硫化钼粉为过200-400目微米级粉。
优选地,步骤(3)中加压循环时的压力为1-3大气压。
优选地,步骤(6)中所述树脂胶为固含量为45-55%的脲醛树脂胶,施胶量为100-120g/m2。
优选地,所述步骤(2)中所述片板尺寸为:长度800-2200mm,宽800-2200mm,厚度2-5mm。
本发明具有以下优点:
本发明的加工设备,通过一定时间的循环,可以使碳纤维纵向分布,提高了多层复合地板的导热性能。
本发明的加工方法,采用在密封容器内进行加压定向浸渍,可是使碳纤维纵向分布,提高了多层复合木板的导热性能,且可以定向导热。同时,加入一定量的导热碳纤维粉、氧化铝、二硫化钼粉,使地板的导热性能进一步提高。
本发明将一定量的水玻璃渍入片板内部,填充了片板内部的部分微孔,降低了树脂进入片板内部的量,减少了树脂的用量,从而降低了甲醛的释放。
